ExecutorExt

[MajorBreakfast]

The executor trait looks like this:

pub trait Executor {
    fn spawn_obj(
        &mut self,
        future: FutureObj<'static, ()>,
    ) -> Result<(), SpawnObjError>;

    fn status(&self) -> Result<(), SpawnErrorKind> { ... }

    // Planned
    fn spawn(
        &mut self,
        future: dyn Future<Output = ()> + Send + 'static,
    ) -> Result<(), SpawnError> { ... }
}

And here's how using it looks like (uses upcoming boxed combinator):

ctx.executor().spawn_obj(future.boxed().into());

// Planned
ctx.executor().spawn(future);

I would like to define ExecutorExt:

pub trait ExecutorExt {
    fn spawn_obj_with_handle<T>(
        &mut self,
        future: FutureObj<'static, T>,
    ) -> Result<JoinHandle<T>, SpawnObjError>;

    // Planned
    fn spawn_with_handle<T>(
        &mut self,
        future: dyn Future<Output = T> + Send + 'static,
    ) -> Result<JoinHandle<T>, SpawnError>;
}

TL;DR Move our existing spawn_with_handle function into ExecutorExt
